Penn State Nittany Lions: B1G spring positions 14

We're taking snapshots of each position group with every Big Ten team entering the spring. The series wraps up with the specialists.

Illinois:The Illini might not be exceptional in the kicking game, but they're in better shape than they were when coach Tim Beckman arrived. Punter Justin DuVernois returns after a solid junior season, while Taylor Zalewski looks for a bit more consistency in his second full season as the placekicker. Zalewski made 12 of 17 field-goal attempts last fall. The return game is the real plus, as V'Angelo Bentley provides a major threat, especially on punt returns.

Indiana: Like Illinois, Indiana brings back a dynamic returner in Shane Wynn, who averaged 14 yards on punt run-backs despite limited work. Punter Erich Toth also is back for his third season as the starter. Toth placed 18 of 52 attempts inside the opponent's 20-yard line. IU suffers a big loss at kicker as Mitch Ewald, the team's career field goals and field-goal percentage leader, departs. Aaron Del Grosso and Griffin Oakes will compete at kicker, and Jake Shake (shake and bake!) could enter the mix this summer.

Iowa: Here's another Big Ten team that looks very strong on returns, as Iowa boasts the Big Ten's most dynamic tandem in Kevonte Martin-Manley (punts) and Jordan Cotton (kickoffs). Martin-Manley had two punt-return touchdowns in 2013. Punter Connor Kornbrath ranked near the bottom of the Big Ten in average, but placed 27 of 65 attempts inside the opponent's 20. Iowa loses kicker Mike Meyer, a four-year starter. Junior Marshall Koehn seems likely to step up, but could be pushed by incoming freshman Mick Ellis and others.

Maryland: Notice a theme so far? Most Big Ten teams are strong in the return game, and Maryland is no exception. If Stefon Diggs returns at full strength from his leg injury, he'll be a dangerous man with punts and kickoffs in his hands. Will Likely performed extremely well in Diggs' spot, averaging 26 yards on kickoff returns and 12.8 yards on punt returns. Maryland brings back an excellent kicker in Brad Craddock (21-for-25 on field goals last year), and punter Nathan Renfro enters his third season as the starter.

Michigan: Matt Wile has done a bit of everything for Michigan, but could settle into the starting placekicker role this fall. Wile handled kicking duties late last season and also served as Michigan's punter after Will Hagerup was suspended for the season. Hagerup, the Big Ten's punter of the year in 2012, will reclaim the role if he can avoid off-field problems that have surfaced throughout his career. Wile then could focus on kicking, as Kenny Allen is the only other option there. Michigan is still waiting for big things from kick returner Dennis Norfleet and must find someone to handle punts. Top recruit Jabrill Peppers could help.

Michigan State: Special teams once again should be a strength for MSU, which returns All-Big Ten punter Mike Sadler, a Ray Guy award semifinalist who will contend for All-America honors in 2014. Kicker Michael Geiger also is back after connecting on 15 of 16 field-goal attempts as a true freshman. Macgarrett Kings Jr. and Andre Sims Jr. both put up good numbers on punt returns. Michigan State had by far the fewest kick returns (18) in the Big Ten last year and will look for a boost from R.J. Shelton and others.

Minnesota: After an above-average year on special teams in 2013, Minnesota again should be good in the third phase. Punter Peter Mortell didn't get as many accolades as Sadler or Purdue's Cody Webster, but he had an excellent sophomore season, averaging 43.3 yards per attempt with 15 of 50 yards or longer. Marcus Jones is a major threat on returns after bringing back both a kickoff and a punt for touchdowns last fall. Redshirt freshman kickers Ryan Santoso and Andrew Harte will compete as the Gophers lose Chris Hawthorne.

Nebraska: The Huskers are looking for some upgrades on special teams, particularly on punt returns, as Nebraska ranked 123rd in the FBS last fall. Primary returner Jordan Westerkamp is back, but he'll face some competition. Nebraska brings back punter Sam Foltz, who had a solid freshman season, averaging 41.6 yards per boot. Mauro Bondi is set to step in at kicker as Pat Smith departs. If Bondi struggles, incoming freshman Kris Brown could get a look this summer. Kenny Bell, who led the Big Ten in kick return average (26.5 yards per return), is back.

Northwestern: The Wildcats lose a huge piece in Jeff Budzien, named the Big Ten's top kicker in each of his final two seasons. Hunter Niswander can handle both kickoffs and punts but seems likely to slide into Budzien's spot. Northwestern's punting was a mess in 2013, ranking 118th nationally in net average (33.2 ypp). Brandon Williams departs and Chris Gradone or Niswander will take over. The big news is Northwestern brings back Venric Mark , an All-America punt returner in 2012. Primary kick returner Matt Harris is back after a solid freshman season.

Ohio State: Aussie, Aussie, Aussie. Indeed, the Aussie is back at punter as Cameron Johnston returns after an excellent debut season (I refuse to call a 21-year-old a freshman). Ohio State hopes for similar results from another first-year specialist in kicker Sean Nuernberger, an early enrollee expected to step in for the departing Drew Basil. Sophomore Dontre Wilson will continue to have a big role on returns after handling kickoffs last year. Ohio State must replace Corey Brown on punt returns and could look to redshirt freshman Jalin Marshall or true freshmen Curtis Samuel and Johnnie Dixon.

Penn State: The kicking game continues to be an area of concern.Sam Ficken owns the team record for consecutive field goals (15) and started strong last season but ended with just 15 of 23 conversions, including four misses inside 40 yards. Penn State needs a new punter after losing Alex Butterworth, and will turn to Chris Gulla. Jesse Della Valle did a good job on punt returns, but Penn State needs a boost on kickoffs after finishing last in the league (19.1 yards per return). The Lions could stick with Geno Lewis or look for a newcomer such as De'Andre Thompkins to emerge. PSU also must shore up its coverage units.

Purdue: As if the Boilers didn't have enough to address on offense and defense, the kicking game needs attention. Punter Cody Webster finished his spectacular career with All-America honors, and the Boilers finished second nationally in net punting (41.7 yards per punt). Incoming freshman Austin McGehee will take over for Webster. Paul Griggs and Thomas Meadows continue to work at kicker, as Griggs made only 50 percent of his attempts (6 of 12) last season. The kick return game is strong with Akeem Hunt and Raheem Mostert, but Purdue must replace punt returner Ricardo Allen. B.J. Knauf could be a good fit there.

Rutgers: The kicking game historically is a strength for Rutgers, which has a knack for blocking kicks and pulling off fakes. Rutgers loses a productive piece in punter Nick Marsh, who also handled kickoffs. The Scarlet Knights will turn to Joseph Roth as their replacement. Kicker Kyle Federico finished the season well, particularly in the Pinstripe Bowl, and returns for his junior season. Rutgers has a major weapon on returns in Janarion Grant, who brought back both a punt and a kickoff for a touchdown during his freshman season.

Wisconsin: The kicking game has held back Wisconsin in the past, so it's definitely an area to watch during the offseason. Kicker Jack Russell converted 9 of 13 field-goal attempts after taking over for Kyle French. He'll try to hold off incoming freshman Rafael Gaglianone. Andrew Endicott, who handled kickoffs last fall, also returns. Wisconsin is looking for more from punter Drew Meyer, who averaged just 38.6 yards per attempt in 2013. Top returner Kenzel Doe is back and should handle both punts and kickoffs, although Wisconsin could look to others for help, such as newcomers Serge Trezy and Natrell Jamerson.

We're taking snapshots of each position group with every Big Ten team entering the spring. Up next: the defensive backs.

Illinois: The secondary returns mostly intact from 2013, as Illinois returns starters at both cornerback spots (V'Angelo Bentley and Eaton Spence), as well as Zane Petty, who started the final seven games at free safety. Taylor Barton, who opened last season as a starting free safety, also is back. Building safety depth is important this spring as Illinois must replace Earnest Thomas III. Barton will compete with Jevaris Little and others for playing time. The depth is much better at corner as Darius Mosely and Jaylen Dunlap both saw significant action as freshmen last fall.

Indiana: Like Illinois, Indiana returns a lot in the defensive backfield but must improve after struggling to stop opponents in 2013. The Hoosiers also lose only one starter in safety Greg Heban, a mainstay during the past four seasons. There's a lot of experience at cornerback with returning starters Tim Bennett (senior) and Michael Hunter (junior), along with reserve Kenny Mullen (senior). Decorated recruit Rashard Fant, who redshirted in 2013, will compete for significant playing time. Senior safety Mark Murphy will lead the secondary, and sophomore Antonio Allen could fill the other safety spot when he returns from an ACL tear. Building depth here always is a priority at IU.

Iowa: The situation isn't as dramatic as the linebacker spot, but Iowa still must replace two productive players in cornerback B.J. Lowery and safety Tanner Miller, who combined for six interceptions in 2013. Lowery is the more significant loss, as he had 19 passes defended and three forced fumbles. The good news is Desmond King looks like a budding star and he will move into the featured role Lowery occupied. Jordan Lomax, Sean Draper and others will compete to start opposite King. Strong safety John Lowdermilk returns after a solid junior season. Lomax also could play free safety and will compete there with Anthony Gair and Nico Law, who both appeared in all 13 games last fall as reserves.

Maryland: The back four aims for better results on the injury front and on the field in 2013. Maryland returns both starters at safety in Sean Davis, the team's leading tackler with 102 last fall, and Anthony Nixon, but there should be competition behind them with A.J. Hendy and Zach Dancel. The cornerback position is worth watching this spring as Dexter McDougle departs and Jeremiah Johnson remains limited by a toe injury. Will Likely has opened the spring as a starter, and Alvin Hill could rise up after recording 24 tackles last season.

Michigan: The secondary took a step back in 2013 and all jobs are open even though Michigan returns two veteran cornerbacks -- Blake Countess and Raymon Taylor -- and some experience at safety. Jabrill Peppers, the nation's No. 2 overall recruit according to ESPN Recruiting Nation, will play a major role for the Wolverines this fall, whether it's at corner, safety or nickel. Junior Jarrod Wilson started the first seven games of last season at free safety, and Dymonte Thomas is a good candidate to start at one of the safety spots. Michigan should expect more from this group in 2014.

Nebraska: An important spring awaits new defensive backs coach Charlton Warren, who must identify new starters at cornerback, safety and nickel. The Huskers are replacing Ciante Evans and Stanley Jean-Baptiste, who combined for eight interceptions, 18 passes defended and 15 tackles for loss in 2013. Safety Andrew Green, who made 10 starts in 2013, also leaves. The good news is cornerback Josh Mitchell had an excellent bowl game and will fill a starting spot. Leading tackler Corey Cooper also returns at safety. There's not much experience at corner other than Mitchell, and Daniel Davie, Auburn transfer Jonathan Rose and others will compete. Nebraska brings back more at safety with Harvey Jackson, who made three starts in 2013, and junior Charles Jackson.

Northwestern: That the Wildcats' secondary could be one of the team's biggest strengths seemed laughable three years ago, but it could be true this fall. All four starters return, led by safety Ibraheim Campbell, one of the Big Ten's most productive defenders (262 career tackles). The depth at cornerback looks strong as starters Nick VanHoose and Matt Harris return, along with Dwight White and Daniel Jones, who opened 2013 as a starter and is coming back from an ACL tear. Traveon Henry should start alongside Campbell, and there are some promising young safeties like Godwin Igwebuike.

Ohio State: Pass defense proved to be Ohio State's downfall in 2013, and the Buckeyes' secondary will be under the microscope this spring as new assistant Chris Ash steps in. Ohio State loses All-Big Ten cornerback Bradley Roby and will lean more on Doran Grant, who started opposite Roby in 2013. Ash also expects big things from Tyvis Powell, who will start at one of the safety spots. Safety Vonn Bell finally logged significant playing time in the Orange Bowl and could become a permanent starter as a sophomore. Veteran Ron Tanner and Cam Burrows also are in the mix at safety. There should be good competition to start opposite Grant, as Armani Reeves tries to hold off redshirt freshmen Gareon Conley and Eli Apple.

Penn State: After a season of moving parts and inconsistent plays, Penn State hopes for a more settled secondary. Adrian Amos, who alternated between cornerback and safety last season, will lead the group and brings plenty of experience. Jordan Lucas likely will start opposite Amos at cornerback after making strides toward the end of his sophomore season. PSU loses some leadership at safety with Malcolm Willis and Stephen Obeng-Agyapong departing and will lean on Ryan Keiser and Jesse Della Valle, both of whom have starting experience. Converted wideouts Trevor Williams and Malik Golden provide depth at cornerback and safety, respectively.

Purdue: The rotation from 2013 returns almost completely intact, but Purdue loses a very big piece in cornerback Ricardo Allen, a four-year starter. Cornerback Frankie Williams enters his third year as a starter and will slide into Allen's featured role, while the competition for the other top corner spot will feature Antoine Lewis and Leroy Clark, among others. Purdue has plenty of experience at safety with Taylor Richards, who started every game in 2013, and Anthony Brown, who replaced the injured Landon Feichter and had 69 tackles. Feichter also is back from a broken leg.

We're taking snapshots of each position group with each Big Ten team entering the spring. Up next: the linebackers.

Illinois: The Illini lose an All-Big Ten player in Jonathan Brown but still have decent overall depth at linebacker. Mason Monheim started every game at middle linebacker in 2013, and Mike Svetina started all but one game at the star position. Both players return as juniors. Svetina will move into Brown's spot on the weak side, while the other position could be filled by T.J. Neal, who recorded 38 tackles last season. Ralph Cooper has logged significant reps as a reserve, and Eric Finney gives Illinois some flexibility after playing the star position (safety/outside linebacker).

Indiana: This becomes a more significant position under coordinator Brian Knorr, who plans to use a 3-4 alignment. Indiana should have enough depth to make the transition as it returns two full-time starters from 2013 -- David Cooper and T.J. Simmons -- as well as two part-time starters in Forisse Hardin and Clyde Newton, who started the final four games of his freshman season. Like Simmons and Newton, Marcus Oliver played a lot as a freshman and provides some depth. The key here will be converting all the experience into sharper, more consistent play.

Iowa: If you're of the mindset that Iowa always reloads at linebacker, you can rest easy this spring. If not, keep a very close eye on what happens as the Hawkeyes begin replacing one of the more productive linebacker groups in team history: James Morris, Christian Kirksey and Anthony Hitchens. There are high hopes for sophomore Reggie Spearman, who played in 10 games as a freshman last fall. Spearman, junior Travis Perry and senior Quinton Alston enter the spring as the front-runners to take over the top spots. The biggest challenge could be building depth behind them with Cole Fisher and others.

Maryland: The good news is the Terrapins return three productive starters from 2013 in Cole Farrand, L.A. Goree and Matt Robinson, who combined for 233 tackles, including 19 for loss. The bad news is Maryland loses its top playmaker at the position in Marcus Whitfield, who recorded nine sacks and 15.5 tackles for loss last season. But the overall picture is favorable, and the depth should be strong when Alex Twine and Yannik Cudjoe-Virgil return from their injuries. Young players such as Abner Logan (37 tackles in 2013) will push for more time.

Michigan: There are a lot of familiar faces in new positions as Michigan not only has shuffled the roles of its defensive assistant coaches, but also its top linebackers. Standout Jake Ryan moves from strong-side linebacker to the middle, while junior James Ross III moves from the weak side to the strong side and Desmond Morgan shifts from the middle to the weak side. Joe Bolden, who had 54 tackles last season, can play both outside and inside, and players such as Ben Gedeon, Royce Jenkins-Stone and Allen Gant add depth. The talent is there for a big year if the position switches pan out.

Michigan State: It won't be easy to replace the Big Ten's top linebacker tandem in Max Bullough and Denicos Allen, not to mention Rose Bowl hero Kyler Elsworth, but Michigan State has some promising options. Ed Davis appears ready to step in for Allen after recording four sacks as a sophomore. Junior Darien Harris and two redshirt freshmen, Shane Jones and Jon Reschke, will compete at middle linebacker. Returning starter Taiwan Jones is back at the star position, and Mylan Hicks should be in the rotation. Depth is a bit of a question mark here entering the spring.

Minnesota: The Gophers lose key pieces in all three areas of the defense, and linebacker is no exception as two starters (Aaron Hill and James Manuel) depart. Minnesota will lean on Damien Wilson, who started in 12 games at middle linebacker in his first season with the Gophers and recorded 78 tackles. Junior De'Vondre Campbell seems ready to claim a starting spot after backing up Manuel last season. There will be plenty of competition at the strong-side linebacker spot, as Nick Rallis, De'Niro Laster and others are in the mix. Jack Lynn is backing up Wilson at middle linebacker but could work his way into a starting spot on the outside with a good spring.

Nebraska: Optimism is building for the Blackshirts in 2014, thanks in large part to the returning linebackers. The three players who finished last season as the starters -- David Santos, Michael Rose and Zaire Anderson -- all are back, as Rose will lead the way in the middle. Josh Banderas and Nathan Gerry also have starting experience and return for 2014. If younger players such as Marcus Newby develop this spring, Nebraska could have the Big Ten's deepest group of linebackers, a dramatic departure from the Huskers' first few years in the conference. Good things are happening here.

Northwestern: The top two playmakers return here in Chi Chi Ariguzo and Collin Ellis, who combined for seven interceptions and 11.5 tackles for loss in 2014. Northwestern's challenge is replacing the leadership Damien Proby provided in the middle. Ellis has shifted from the strong side to the middle, and Northwestern has moved safety Jimmy Hall from safety to strong-side linebacker. Drew Smith and Hall will compete for the third starting spot throughout the offseason. Sophomores Jaylen Prater and Joseph Jones should provide some depth.

Ohio State: Coach Urban Meyer has made it clear that Ohio State needs more from the linebackers, so it's a huge offseason for this crew, which loses superstar Ryan Shazier. The Buckeyes return starters at the outside spots in Curtis Grant and Joshua Perry, although competition will continue throughout the spring and summer. Redshirt freshman Darron Lee surprisingly opened spring practice Tuesday working with Grant and Perry on the first-team defense. Camren Williams appeared in all 13 games as a reserve and will be part of the rotation, along with Trey Johnson. Meyer said last month that the incoming linebacker recruits won't redshirt, which means an opportunity for mid-year enrollee Raekwon McMillan.

Penn State: Linebacker U is looking for more bodies at the position after struggling with depth issues throughout 2013. The Lions lose leading tackler Glenn Carson but bring back two players, Mike Hull and Nyeem Wartman, who started most of the season. The new coaching staff is counting on Hull to become a star as a senior. Brandon Bell, who appeared in nine games and recorded 24 tackles as a freshman, will compete for a starting spot along with Gary Wooten. Penn State hopes Ben Kline can stay healthy as he provides some experience, and incoming freshman Troy Reeder could enter the rotation right away.

Purdue: Expect plenty of competition here as Purdue loses leading tackler Will Lucas and must get more consistent play from the group. Joe Gilliam started for most of the 2013 season and should occupy a top spot this fall. Sean Robinson also brings experience to the field, and Ryan Russell could fill more of a hybrid linebacker/defensive end role this season. Redshirt freshman Danny Ezechukwu is an intriguing prospect to watch this spring as he aims for a bigger role. Ezechukwu is just one of several younger players, including decorated incoming recruit Gelen Robinson, who have opportunities to make a splash.

Rutgers: The Scarlet Knights return a good deal of production here with Steve Longa and Kevin Snyder, who combined for 219 tackles, including 15 tackles for loss and five sacks. Quentin Gause also is back after racking up 53 tackles (8.5 for loss) in a mostly reserve role last season. Gause likely will claim the starting strong-side linebacker spot as Jamal Merrell departs. The starting spots are seemingly set, so Rutgers will look to build depth with Davon Jacobs, who had 30 tackles as a reserve last season, and L.J. Liston, both sophomores.

We're taking snapshots of each position group with each Big Ten team entering the spring. Up next: the defensive lines.

Illinois: This is a significant concern for the Illini, especially after the recent departure of Houston Bates, who started last season at the Leo (defensive end/outside linebacker) spot. Illinois also loses its other starting defensive end, Tim Kynard. The team will rely heavily on junior-college players such as Jihad Ward and Joe Fotu, but it also needs holdovers like Dawuane Smoot and Paul James III to step up on the perimeter. Illinois returns more experience inside with Austin Teitsma and Teko Powell, but there should be plenty of competition, especially with the juco arrivals, after finishing 116th nationally against the run.

Indiana: The anticipated move to a 3-4 alignment under new coordinator Brian Knorr creates a different dynamic for the line this spring. Indiana must identify options at the all-important nose tackle spot, and possibilities include sophomores Ralphael Green and Darius Latham, both of whom are big bodies. Nick Mangieri had a nice sophomore season and should be in the mix for a starting job on the perimeter (end or outside linebacker), while David Kenney could be a good fit as a 3-4 end. Defensive end Ryan Phillis is the team's most experienced lineman, and Zack Shaw also has some starting experience.

Iowa: This group should be the strength of the defense as Iowa returns three full-time starters -- tackles Carl Davis and Louis Trinca-Pasat, and end Drew Ott -- as well as Mike Hardy, who started the second half of the season opposite Ott. End Dominic Alvis departs, but Iowa brings back almost everyone else from a line that allowed only eight rushing touchdowns in 2013. Junior Darian Cooper could have a bigger role and push for more playing time inside, and Nate Meier provides some depth on the perimeter after recording two sacks in 2013. Iowa is in good shape here.

Maryland: The Terrapins employ a 3-4 scheme and appear to be in good shape up front, as reserve Zeke Riser is the only rotation player to depart. Andre Monroe leads the way at defensive end after an excellent junior season in which he led Maryland in both sacks (9.5) and tackles for loss (17). Quinton Jefferson started at defensive end last season and recorded three sacks. There should be some good competition this spring at nose tackle between Keith Bowers and Darius Kilgo, both of whom had more than 30 tackles last season. The challenge is building greater depth with players such as end Roman Braglio.

Michigan: If the Wolverines intend to make a big step in 2014, they'll need more from the front four, which didn't impact games nearly enough last fall. Michigan's strength appears to be on the edges as veteran Frank Clark returns after starting every game in 2013 and recording a team-high 12 tackles for loss. Brennen Beyer, who started the second half of last season, is back at the other end spot, and Michigan has depth with Mario Ojemudia and Taco Charlton. There are more questions inside as Willie Henry, Chris Wormley and others compete for the starting job. Young tackles such as Henry Poggi and Maurice Hurst Jr. also are in the mix, and Ondre Pipkins should be a factor when he recovers from ACL surgery.

Minnesota: Defensive tackles like Ra'Shede Hageman don't come around every year, and he leaves a big void in the middle of Minnesota's line. The Gophers will look to several players to replace Hageman's production, including senior Cameron Botticelli, who started opposite Hageman last season. Other options at tackle include Scott Ekpe and Harold Legania, a big body at 308 pounds. Minnesota is in much better shape at end with Theiren Cockran, arguably the Big Ten's most underrated defensive lineman. Cockran and Michael Amaefula both started every game last season, and Alex Keith provides another solid option after recording five tackles for loss in 2013.

Nebraska: Other than MSU's Calhoun, Nebraska returns the most dynamic defensive lineman in the league in Randy Gregory, who earned first-team All-Big Ten honors in his first FBS season. If the Huskers can build around Gregory, they should be very stout up front this fall. Nebraska won't have Avery Moss, suspended for the 2014 season, and players such as Greg McMullen and junior-college transfer Joe Keels will compete to start opposite Gregory. The competition inside should be fascinating as junior Aaron Curry and sophomore Vincent Valentine both have starting experience, but Maliek Collins came on strong at the end of his first season and will push for a top job.

Northwestern: It will be tough to get a clear picture of this group in the spring because of several postseason surgeries, but Northwestern should be fine at defensive end despite the loss of Tyler Scott. Dean Lowry, Ifeadi Odenigbo and Deonte Gibson all have significant experience and the ability to pressure quarterbacks. Odenigbo, who had 5.5 sacks as a redshirt freshman, could become a star. The bigger questions are inside as Northwestern must build depth. Sean McEvilly is a solid option but must stay healthy. Chance Carter and Max Chapman are among those competing for starting jobs at tackle.

Ohio State: A total mystery last spring, the defensive line should be one of Ohio State's strengths in 2014. Noah Spence and Joey Bosa could become the Big Ten's top pass-rushing tandem, and the Buckeyes have depth there with Jamal Marcus, Adolphus Washington and others. Returning starter Michael Bennett is back at defensive tackle, and while Joel Hale might move to offense, there should be enough depth inside with Tommy Schutt, Chris Carter and Washington, who could slide inside. Nose tackle is the only question mark, but new line coach Larry Johnson inherits a lot of talent.

Penn State: Like the rest of the Lions defense, the line struggled at times last season and now much replace its top player in tackle DaQuan Jones. The new coaching staff has some potentially good pieces, namely defensive end Deion Barnes, who won 2012 Big Ten Freshman of the Year honors but slumped as a sophomore. Barnes and C.J. Olaniyan could form a dangerous pass-rushing tandem, but they'll need support on the inside, where there should be plenty of competition. Austin Johnson will be in the mix for a starting tackle spot, and early enrollees Tarow Barney and Antoine White also should push for time. Anthony Zettel provides some depth on the perimeter.

Purdue: The line endured a tough 2013 campaign and loses two full-time starters (tackle Bruce Gaston Jr. and end Greg Latta), and a part-time starter (end Ryan Isaac). Competition should be ramped up at all four spots this spring. Senior end Ryan Russell is the most experienced member of the group must take a step this offseason. Evan Panfil and Jalani Phillips will push for time at the end spots, along with Kentucky transfer Langston Newton. The group at tackle includes Ryan Watson and Michael Rouse III, both of whom started games in 2013.

Rutgers: Keep a close eye on this group in the spring as Rutgers begins the transition to the Big Ten. The Scarlet Knights lose two starters in end Marcus Thompson and tackle Isaac Holmes, as well as contributor Jamil Merrell at tackle. Darius Hamilton provides a building block on the inside after recording 4.5 sacks and 11.5 tackles for loss in 2013, and end Djwany Mera is back after starting throughout last season. David Milewski played tackle last year, but both he and Hamilton likely need to add weight for their new league. Rutgers has some talent in the younger classes and needs players such as Sebastian Joseph, Kemoko Turay and Julian Pinnix-Odrick to emerge.

Wisconsin: Linebacker Chris Borland is the biggest single departure for the Badgers' defense, but the no position group loses more than the line. Wisconsin must replace several mainstays, most notably nose tackle Beau Allen, who performed well in the first year of the 3-4 set under coordinator Dave Aranda. Senior Warren Herring will step in for Allen after three years as a reserve. Konrad Zagzebski is a good bet to fill one of the end spots, but there will be plenty of competition with players such as Jake Keefer, James Adeyanju, Arthur Goldberg and Chikwe Obasih.

We're taking snapshots of each position group with each Big Ten team entering the spring. Up next: the big uglies.

Illinois: This is another group that appears to be in significantly better shape now than at the start of coach Tim Beckman's tenure. The Illini lose only one full-time starter in tackle Corey Lewis, as four other linemen who started at least eight games in 2013 return. Senior tandem Michael Heitz and Simon Cvijanovic are two of the Big Ten's most experienced linemen, and guards Ted Karras also has logged plenty of starts. Right tackle appears to be the only vacancy entering the spring, as Austin Schmidt and others will compete.

Indiana: The Hoosiers have somewhat quietly put together one of the Big Ten's best offensive lines, and the same should hold true in 2014. Everybody is back, and because of injuries before and during the 2013 season, Indiana boasts a large group with significant starting experience. Jason Spriggs should contend for first-team All-Big Ten honors as he enters his third season at left tackle. Senior Collin Rahrig solidifies the middle, and Indiana regains the services of guard Dan Feeney, who was sidelined all of 2013 by a foot injury.

Iowa: The return of left tackle Brandon Scherff anchors an Iowa line that could be a team strength this fall. Scherff will enter the fall as a leading candidate for Big Ten offensive lineman of the year. Iowa must replace two starters in right tackle Brett Van Sloten and left guard Conor Boffeli. Andrew Donnal could be the answer in Van Sloten's spot despite playing guard in 2013, while several players will compete at guard, including Tommy Gaul and Eric Simmons. Junior Austin Blythe returns at center.

Maryland: Line play will go a long way toward determining how Maryland fares in the Big Ten, and the Terrapins will make the transition with an experienced group. Four starters are back, led by center Sal Conaboy, who has started games in each of his first three seasons. Tackles Ryan Doyle and Michael Dunn bring versatility to the group, and Maryland should have plenty of options once heralded recruit Damian Prince and junior-college transfer Larry Mazyck arrive this summer. Prince is the top Big Ten offensive line recruit in the 2014 class, according to ESPN RecruitingNation. New line coach Greg Studwara brings a lot of experience to the group.

Michigan: The Wolverines' line is under the microscope this spring after a disappointing 2013 season. Michigan loses both starting tackles, including Taylor Lewan, the Big Ten's offensive lineman of the year and a projected first-round draft choice. The interior line was in flux for much of 2013, and Michigan needs development from a large group of rising sophomores and juniors, including Kyle Kalis, Kyle Bosch, Jack Miller, Graham Glasgow, and Patrick Kugler. Both starting tackle spots are open, although Ben Braden seems likely to slide in on the left side. Erik Magnuson is out for spring practice following shoulder surgery, freeing up opportunities for redshirt freshman David Dawson and others.

Michigan State: The line took a significant step forward in 2013 but loses three starters, including left guard Blake Treadwell, a co-captain. Michigan State used an eight-man rotation in 2013 and will look for development from top reserves such as Travis Jackson (Yes! Yes!) and Connor Kruse. Kodi Kieler backed up Treadwell last season and could contend for a starting job as well. Coach Mark Dantonio said this week that converted defensive linemen James Bodanis, Devyn Salmon and Noah Jones will get a chance to prove themselves this spring. It's important for MSU to show it can reload up front, and the large rotation used in 2013 should help.

Minnesota: For the first time since the Glen Mason era, Minnesota truly established the line of scrimmage and showcased the power run game in 2013. The Gophers return starters at four positions and regain Jon Christenson, the team's top center before suffering a season-ending leg injury in November. Right tackle Josh Campion and left guard Zac Epping are mainstays in the starting lineup, and players such as Tommy Olson and Ben Lauer gained some valuable experience last fall. There should be good leadership with Epping, Olson, Marek Lenkiewicz and Caleb Bak.

Nebraska: Graduation hit the line hard as five seniors depart, including 2012 All-American Spencer Long at guard and Jeremiah Sirles at tackle. Nebraska will lean on guard Jake Cotton, its only returning starter, and experienced players such as Mark Pelini, who steps into the center spot. Senior Mike Moudy is the top candidate at the other guard spot, but there should be plenty of competition at the tackle spots, where Zach Sterup, Matt Finnin and others are in the mix. Definitely a group to watch this spring.

Northwestern: Offensive line struggles undoubtedly contributed to Northwestern's disappointing 2013 season. All five starters are back along with several key reserves, and coach Pat Fitzgerald already has seen a dramatic difference in the position competitions this spring as opposed to last, when many linemen were sidelined following surgeries. Center Brandon Vitabile is the only returning starter who shouldn't have to worry about his job. Paul Jorgensen and Eric Olson opened the spring as the top tackles, and Jack Konopka, who has started at both tackle spots, will have to regain his position.

Ohio State: Like Nebraska, Ohio State enters the spring with a lot to replace up front as four starters depart from the Big Ten's best line. Taylor Decker is the only holdover and will move from right tackle to left tackle. Fifth-year senior Darryl Baldwin could step in at the other tackle spot, while Pat Elflein, who filled in for the suspended Marcus Hall late last season, is a good bet to start at guard. Jacoby Boren and Billy Price will compete at center and Joel Hale, a defensive lineman, will work at guard this spring. Ohio State has recruited well up front, and it will be interesting to see how young players such as Evan Lisle and Kyle Dodson develop.

Penn State: New coach James Franklin admits he's concerned about the depth up front despite the return of veterans Miles Dieffenbach and Donovan Smith on the left side. Guard Angelo Mangiro is the other lineman who logged significant experience in 2013, and guard/center Wendy Laurent and guard Anthony Alosi played a bit. But filling out the second string could be a challenge for Penn State, which could start a redshirt freshman (Andrew Nelson) at right tackle. The Lions have to develop some depth on the edges behind Nelson and Smith.

Purdue: The Boilers reset up front after a miserable season in which they finished 122nd out of 123 FBS teams in rushing offense (67.1 ypg). Three starters return on the interior, led by junior center Robert Kugler, and there's some continuity at guard with Jordan Roos and Justin King, both of whom started as redshirt freshmen. It's a different story on the edges as Purdue loses both starting tackles. Thursday's addition of junior-college tackle David Hedelin could be big, if Hedelin avoids a potential NCAA suspension for playing for a club team. Cameron Cermin and J.J. Prince also are among those in the mix at tackle.

Rutgers: Continuity should be a strength for Rutgers, which returns its entire starting line from 2013. But production has to be better after the Scarlet Knights finished 100th nationally in rushing and tied for 102nd in sacks allowed. Guard Kaleb Johnson considered entering the NFL draft but instead will return for his fourth season as a starter. Rutgers also brings back Betim Bujari, who can play either center or guard, as well as Keith Lumpkin, the likely starter at left tackle. It will be interesting to see if new line coach Mitch Browning stirs up the competition this spring, as younger players Dorian Miller and J.J. Denman could get a longer look.

Wisconsin: There are a lot of familiar names up front for the Badgers, who lose only one starter in guard Ryan Groy. The tackle spots look very solid with Tyler Marz (left) and Rob Havenstein (right), and Kyle Costigan started the final 11 games at right guard. There should be some competition at center, as both Dan Voltz and Dallas Lewallen have battled injuries. Coach Gary Andersen mentioned on national signing day that early enrollee Michael Deiter will enter the mix immediately at center. Another early enrollee, decorated recruit Jaden Gault, should be part of the rotation at tackle. If certain young players develop quickly this spring, Wisconsin should have no depth issues when the season rolls around.

We're taking snapshots of each position group with each Big Ten team entering the spring. The wide receivers and tight ends are up next.

Illinois: The Illini are looking for more from this group after losing top target Steve Hull, who exploded late in the season to finish just shy of 1,000 receiving yards. While running back Josh Ferguson (50 catches in 2013) will continue to contribute, Illinois could use a boost from Martize Barr, who arrived with high expectations but only had 26 receptions last fall. Another junior-college transfer, Geronimo Allison, could make an impact beginning this spring, but there's some mystery at wideout. Illinois looks more solid at tight end with seniors Jon Davis and Matt LaCosse.

Indiana: Despite the somewhat surprising early departure of All-Big Ten selection Cody Latimer, Indiana should be fine here. Shane Wynn is the veteran of the group after recording 633 receiving yards on 46 catches last season. Kofi Hughes and Duwyce Wilson also depart, so Indiana will be leaning more on Nick Stoner and Isaiah Roundtree. The Hoosiers have high hopes for early enrollee Dominique Booth, a decorated recruit who could fill Latimer's spot on the outside. Productive tight end Ted Bolser departs and several players will compete, including early enrollee Jordan Fuchs.

Iowa: Almost all the wide receivers are back from a group in which none eclipsed more than 400 receiving yards in 2013. Balance is nice, but separation could be nicer for the Hawkeyes this spring. Kevonte Martin-Manley is the most experienced wideout and has 122 career receptions. Tevaun Smith also returns, and Iowa fans are excited about big-play threat Damond Powell, who averaged 24.2 yards on only 12 receptions last season. Iowa loses its top red-zone target in tight end C.J. Fiedorowicz and will need Jake Duzey to deliver more Ohio State-like performances.

Maryland: When the Terrapins get healthy, they might have the Big Ten's best wide receiving corps. Stefon Diggs and Deon Long, both of whom sustained broken legs against Wake Forest last season, have the ability to stretch the field as both averaged more than 15 yards per reception before the injuries struck. Leading receiver Levern Jacobs also returns, alongside junior Nigel King and sophomore Amba Etta-Tawo, who averaged more than 16 yards per catch in 2013. Marcus Leak, who started seven games in 2012, rejoins the team after a year away. The Terps are unproven at tight end after losing Dave Stinebaugh.

Michigan: There's a reason why some Michigan fans want Devin Gardner to return to wide receiver for his final season. The Wolverines are thin on the perimeter after losing Jeremy Gallon and Drew Dileo. Redshirt sophomores Jehu Chesson and Amara Darboh are both candidates to start, and Dennis Norfleet could be the answer in the slot. But there's plenty of opportunity for younger players like Drake Harris, an early enrollee. Michigan's best pass-catching option, Devin Funchess, is listed as a tight end but plays more like a receiver. The Wolverines will be without their second-string tight end, Jake Butt, who suffered an ACL tear in winter conditioning.

Michigan State: Remember all the justified angst about this group a year ago? It has pretty much gone away as the Spartans wideouts rebounded nicely in 2013. Bennie Fowler departs, but MSU brings back its top two receivers in Tony Lippett and Macgarrett Kings, who showed explosiveness down the stretch last fall. Aaron Burbridge had a bit of a sophomore slump but provides another option alongside veteran Keith Mumphery, who averaged 16.6 yards per catch in 2013. Josiah Price leads the tight end group after a solid freshman season.

Minnesota: Here's a group to watch during spring practice, particularly the wide receivers. Minnesota has proven it can run the ball and defend under Jerry Kill, but the passing game was putrid in 2013, ranking last in the Big Ten and 115th nationally. Youth is partly to blame, and while the Gophers still lack experience, they can expect more from promising players like Drew Wolitarsky and Donovahn Jones. Senior Isaac Fruechte provides a veteran presence. Minnesota looks solid at tight end with sophomore Maxx Williams, the team's receiving yards leader (417) in 2013.

Nebraska: The Huskers lose a significant piece in Quincy Enunwa, who led the team in receiving yards (753) and had three times as many receiving touchdowns (12) as anyone else in 2013. Kenny Bell is set to recapture the No. 1 receiver role, which he had in 2012, and comes off of a 52-catch season as a junior. Nebraska must build around Bell this spring with players like the mustachioed Jordan Westerkamp, who had 20 catches as a freshman, including a rather memorable one to beat Northwestern. Will Jamal Turner turn the corner this offseason? Juniors Sam Burtch and Taariq Allen also return. Cethan Carter started six games at tight end last fall and should take over the top spot there as Jake Long departs.

Northwestern: The passing game fell short of expectations in 2013, but there's reason for optimism as Northwestern returns its top three pass-catchers in Tony Jones, Christian Jones and Dan Vitale. The two Joneses (no relation), who combined for 109 catches in 2013, lead the receiving corps along with junior Cameron Dickerson. Speedy Rutgers transfer Miles Shuler provides a playmaking spark, possibly at slot receiver. Vitale, who had a somewhat disappointing sophomore season, has All-Big Ten potential at the superback (tight end) spot. Although Northwestern rarely plays true freshmen, superback Garrett Dickerson, Cameron's brother, could see the field right away.

Ohio State: A group that drew heavy criticism from coach Urban Meyer two springs ago is stockpiling talent. Devin Smith is the familiar name, a big-play senior who has started each of the past two seasons and boasts 18 career touchdowns. Ohio State must replace top wideout Corey Brown and will look for more from Evan Spencer. Michael Thomas has stood out in practices but must translate his performance to games. This could be a breakout year for H-back Dontre Wilson, who averaged nine yards per touch as a freshman. Buckeyes fans are eager to see redshirt freshmen Jalin Marshall and James Clark, and incoming players like Johnnie Dixon could make a splash right away. Ohio State returns an elite tight end in Jeff Heuerman.

Penn State: The Lions have very different depth situations at receiver and tight end. They're looking for contributors on the perimeter after losing Allen Robinson, the Big Ten's top wide receiver the past two seasons, who accounted for 46 percent of the team's receiving production in 2013. Brandon Felder also departs, leaving Geno Lewis as the likeliest candidate to move into a featured role. Richy Anderson also returns, but there will be plenty of competition/opportunity at receiver, a position new coach James Franklin targeted in recruiting with players like Chris Godwin and Saeed Blacknall. Things are much more stable at tight end as the Lions return three talented players in Jesse James, Kyle Carter and Adam Breneman.

Purdue: If you're looking for hope at Purdue, these spots aren't bad places to start. There are several promising young players like receiver DeAngelo Yancey, who recorded a team-leading 546 receiving yards as a freshman. Cameron Posey also had a decent freshman year (26 catches, 297 yards), and Danny Anthrop averaged 18.4 yards as a sophomore. A full offseason with quarterbacks Danny Etling and Austin Appleby should help the group. Tight end also should be a strength as Justin Sinz, who led Purdue with 41 catches last season, is back along with Gabe Holmes, who returns after missing most of 2013 with a wrist injury.

Rutgers: The good news is tight end Tyler Kroft returns after leading Rutgers in both receptions (43) and receiving yards (573) last season. Kroft will immediately contend for All-Big Ten honors. Things are murkier at wide receiver, where top contributors Brandon Coleman and Quron Pratt both depart. Leonte Carroo took a nice step as a sophomore, averaging 17.1 yards per catch and enters the spring as the frontrunner to become the team's No. 1 wideout. Ruhann Peele is another promising young receiver for the Scarlet Knights, who boast size with Carlton Agudosi (6-foot-6) and Andre Patton (6-4).

Wisconsin: The quarterback competition will gain more attention this spring, but Wisconsin's receiver/tight end situation could be more critical. The Badgers lose Jared Abbrederis, their only major threat at receiver the past two seasons, as well as top tight end Jacob Pedersen. Players like Jordan Fredrick and Kenzel Doe must translate their experience into greater production, and Wisconsin will look for more from young receivers like Alex Erickson and Robert Wheelwright. Help is on the way as Wisconsin signed five receivers in the 2014 class, but wideout definitely is a position of concern right now. Sam Arneson is the logical candidate to step in for Pedersen, but there should be competition as the Badgers lose a lot at the position.

Spring practice is off and running in the Big Ten, as Michigan took the field Tuesday and Northwestern followed on Wednesday. We're taking snapshots of where each team stands at each position group.

We've already discussed the quarterbacks -- and will have much more on the way -- so the series begins with the running backs.

Illinois: The Illini are in a bit better shape here than they were the past two springs, as veterans Josh Ferguson and Donovonn Young both return. Ferguson averaged 5.5 yards per carry and added 50 receptions for 535 yards as the primary playmaker for Illinois' revamped offense. Young added 376 yards on 93 carries. The Illini are looking for others behind the top two, and Dami Ayoola is back with the team after being dismissed in September for a rules violation.

Indiana: Tevin Coleman quietly put together a superb sophomore season and leads the Hoosiers' running backs in 2014. Coleman provides big-play ability after averaging 7.3 yards per carry with 12 touchdowns on only 131 attempts in 2013. Indiana loses Stephen Houston but brings back veteran D'Angelo Roberts, who will play behind Coleman. Younger players such as sophomore Laray Smith could get a look here.

Iowa: Not only did the Hawkeyes toss AIRBHG to the side and get through the season without any major injurie, but they bring back everyone for 2014. Senior Mark Weisman leads the contingent after rushing for 975 yards and eight touchdowns last fall. Jordan Canzeri came on strong late in the season and is showing no effects from his ACL tear in 2012. Veteran Damon Bullock also returns to the mix, and Iowa has talented younger backs such as LeShun Daniels Jr. at its disposal. Good situation here.

Maryland: The Terrapins wide receivers tend to get more attention, but the team also returns its top three running backs from 2013 in Brandon Ross, Albert Reid and Jacquille Veii. Maryland also regains the services of Wes Brown, who finished second on the team in rushing as a freshman in 2012 before being suspended for all of last season. Joe Riddle is back in the fold as well. The group brings different strengths, from power (Brown) to speed (Veii) to a mixture of both (Ross, Reid).

Michigan: Sophomore Derrick Green enters the spring as the frontrunner to be Michigan's lead back, although coach Brady Hoke wants to ramp up competition everywhere. The Wolverines struggled to consistently run between the tackles, but the 240-pound Green could change things. Hoke also is excited about another sophomore, De'Veon Smith. Michigan moved Ross Douglas from cornerback to running back, and Justice Hayes and Wyatt Shallman also are in the mix. "We've got more depth," Hoke said.

Michigan State: Things look much more promising than they did last spring, when the Spartans ended the session with a linebacker (Riley Bullough) as their top back. Jeremy Langford emerged as a very solid option during the season, rushing for 1,422 yards and 18 touchdowns. He's back as the clear-cut starter, and Nick Hill also returns. It will be interesting to see if Gerald Holmes makes a push, or whether Delton Williams remains on offense.

Minnesota: Here's another team that finds itself in very good shape at running back entering the spring. David Cobb leads the group after rushing for 1,202 yards and seven touchdowns as a sophomore. Veterans Donnell Kirkwood and Rodrick Williams Jr. are still around, and highly touted redshirt freshman Berkley Edwards will take the field after missing last fall because of knee and ankle injuries. Perhaps the best news will come in the summer as decorated recruit Jeff Jones arrives.

Nebraska: Notice a theme here? Nebraska is yet another Big Ten squad that can feel very good about its running backs entering the spring. Ameer Abdullah elected to bypass the NFL draft for one final season at Nebraska, where he led the Big Ten with 1,690 yards on 281 carries as a junior. Abdullah will contend for national awards in the fall. Imani Cross, who rushed for 10 touchdowns last year, is one of the nation's top backups. Terrell Newby and others add depth behind the top two.

Northwestern: Top back Venric Mark (ankle) will miss spring practice following surgery, and reserve Stephen Buckley (knee) also is rehabbing, but Northwestern has no reason to panic. Treyvon Green, who filled in well for Mark last season with 736 rushing yards, will get much of the work. Warren Long also is in the mix after appearing in seven games as a true freshman. Northwestern also loaded up at running back in recruiting to solidify the position for years to come.

Ohio State: This will be a position to watch in the spring as Ohio State must replace Carlos Hyde, who was nearly unstoppable during Big Ten play last fall. Veteran Jordan Hall also departs, and Rod Smith will be the veteran of the group despite only 83 career carries. The Buckeyes have some talented young backs, from Dontre Wilson, who saw significant playing time last fall, to Bri'onte Dunn, Ezekiel Elliott and Warren Ball. Keep an eye on Elliott, who averaged 8.7 yards per carry in limited work last season but could emerge this spring.

Penn State: If it feels like Zach Zwinak and Bill Belton have been competing for carries forever at Penn State, it's because they have. Zwinak and Belton have been part of Penn State's running back rotation for the past two seasons and enter another competition this spring with talented sophomore Akeel Lynch, who rushed for 358 yards on only 60 carries last season. It will be interesting to see how much Lynch can push Zwinak and Belton in the team's first spring under a new coaching staff. Penn State has depth issues at several positions, but running back isn't one of them.

Purdue: The Boilers finished 122nd nationally in rushing offense last season, so the fact all of their running backs return might not spark mass celebration. Senior Akeem Hunt leads the group after recording 123 of the team's 319 rushing attempts in 2013. Other veteransBrandon Cottom and Raheem Mostert also are back, along with younger ball-carries such as Dayln Dawkins and three backs -- Keyante Green, David Yancey and Keith Byars II -- who redshirted last fall and could have much bigger roles.

Rutgers: Here's yet another team that returns basically its entire stable of running backs for spring ball. Paul James is the name to watch, as he rushed for 573 yards in the first four games last season before suffering a leg injury. James' health is a concern for Rutgers, which could also turn to Justin Goodwin, who showed some flashes following James' injury. Savon Huggins, who entered last season as the starter before losing ground, is in the mix as he looks to re-establish himself on the depth chart.

Wisconsin: How many teams can lose a 1,400-yard rusher and still claim to have the best running back group in the Big Ten? James White is gone, but Wisconsin remains in very good shape in the backfield. Melvin Gordon bypassed the NFL draft for another year in Madison after rushing for 1,609 yards and 12 touchdowns on only 206 carries. Gordon should move into more of a featured role beginning this spring, although he'll be pushed by Corey Clement, who had 547 yards and seven touchdowns on only 67 carries. Jeff Lewis provides another option behind the top two.
